Avahome pointed out this video, which apparently was posted in a comment over on Huffington Post:

In a nutshell, John Dean says: "If the US passes on their moral obligation to investigate this, other countries will step in." Therefore, it will behoove the Obama Administration to address the issue and not drop it.

And remember boys and girls, "pardons" would only prevent prosecution in the US, according to US law. A pardon doesn't mean diddly on the world stage.

UPDATE: From the comments, our intrepid contributor jimstaro points out that he included links to the relevant laws in his recent post "The War Behind Me" -- here they are:

• CHAPTER 113C—TORTURE 18 USC - 2340A
• War crimes 18 USC - 2441
• Genocide 18 USC - 1091

Thanks, Jim!
